SOCIETA' COOPERATIVA OLEIFICIO VAL D'ORCIA SOCIETA' AGRICOLA

Val d'Orcia's cooperative unites olive farmers across Castiglione d'Orcia, a ridge village in Tuscany's southern reaches. Their Terre di Siena DOP extra virgin oil adheres to strict chemistry: acidity under 0.5%, oleic acid exceeding 72%, and 100 ppm polyphenols minimum—measures that anchor this cooperative's reputation in measurable excellence rather than marketing gloss. Pooled harvests and shared milling infrastructure allow small-scale producers to meet export standards while preserving individual terroir expression across the designated 32-municipality zone.
